It's a thrilling battle of the Reverends in 1988, as America chooses between Jesse Jackson and Pat Robertson.
I played '88 with all the normal candidates on as Jackson. Winning the early primaries, it soon became clear I would pull out the primary victory, however Dukakis refused to back out, dragging the primaries out well into June. However, as I expected to win the Dem's nomination, Pat Robertson was the big upset, winning every single Republican primary in a massive wave of momentum. By March 9th every other Republican had pulled out.
With a massive advantage in time and money, Robertson was up by 11% by the time I finally wrapped up the nomination. However I had a few tricks up my sleeve. Accepting the $75,000,000 in public financing, I spent $25,000,000 of it in the first week, garnering a large lead in momentum. This, in itself, lead to every paper endorsing my candidacy, compounding my momentum advantage dramatically. By the end of September I was up by nearly 8 points. I maintained the lead, though it shrunk, through October without spending more then a few million. This allowed me to release several nationwide ads in the last days of the campaign, combining them with 2 medium sized scandals and you have the following result, including a stunner in Texas where Jackson won by a landslide.
